Rotel RB-1510 Troubleshooting, Specifications, Front Panel Power Indicator Is Not Lit, No Sound

10 RB-1510 Stereo Power Amplifier

Troubleshooting

Most difficulties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RB-1510, refer to the suggestions for the following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RB-1510. Check the front panel power switch. Make sure that it is set to the On position. Check AC power connections at the amplifier and the AC outlet.

No Sound

If the amp is getting AC power, but is producing no sound, check the Protection indicator on the front panel. If it is lit, see below. Also check the front panel Level Controls to see if they are turned up. Then check all of your connections and control settings on associated components.

Protection Indicator Is Lit

The front panel indicator lights when the RB-1510 protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself.
